To ALL WHOM IT MAY CONCERN: v

Be it known that I, SAMUEL G. HADLEY, of Cape Vincent, in the county of J efi'erso'n, and State of New York,*havo invented a new and improved Snow-Plough, for use on railroads; and-I do hereby declare that the following is a clear, full, and exact description thereof, reference being had to the accompanying drawing, making part of this specification, andto the letters of reference marked thereon, like letters indicating like parts wherever they occur. v

To enable others skilled in the art to construct and use my invention, I- will proceed to describe it.

Figure 1 is a perspective view. I

Figure 2, a longitudinal vertical section.

Figure 3, a transverse vertical section,-taken on the line a: a: of fig 1.

I first construct a. frame, A, having .its rear end elevated, as shown in figs. 1 and 2 which I mount on wheels in the usual manner. Upon this I mount another frame, B, which latter is hinged at its front end, at a, to the frame A, its rear end being loose; so that it can be raised and adjusted at -varyin-g inclinations, as represented in figs 2, there being a shaft, 0, provided with eccentrics n and levers l, placedtransversely across the frame A for that purpose. I There are also strong braces e, pivoted at their upper ends to the frame B, and having their feet resting in notches in the timbers of frame A, to hold the upper frame securely in position when adjusted.

Upon the frame B, I construct my snow-ploughproper, which consists of'a strong transverse scraper, I, and two spirally inclined chutes C, which latter diverge as they extend backward, and have their inner edges risc' more rapidlylthan their outer ones, thus forming two spiral inclines, as represented in figs. 1 and 2. At each outer edge there is a vertical sidepiece D, the inner surface of which is also curved spirally outward as it extends backward, its front edge being vertical, while its rear end is horizontal, or nearly so, asshown at t. Between the two inclines'C there is a partition, E, the two outer surfaces of which are also formed to curve spirally outward at the rear, as shown in figs. 1 and 2. Both the sides D and the partition E are provided at their front ends with a sharp and strong iron plate, 6, to protect them from injury and wear,and to act as cutters, the

whole being firmly united by a strong cross-bar, L. Within the rear portion of body of the plough I provide an apartment with a look-out, F, at the top, and a door, It, at the rear, for the person in charge, so that he may be in a position to oversee and'properly control the work to be performed. The chutes C are made wider at rear than in front, so that the snow will have a continually increasing space through which to pass, and thus prevent it from clogging or choking up the plough.

By this method of constructing the plough, and by having it so arranged thatit can be adjusted at difi'erent angles or inclinations,I am enabled to produce a snow-plough that will perform its work with dispatch, in either heavy and moist or dry and light snows. I

-Having thus described my invention, what I claim is .1. A snow-plough, having the two spirally-inclined chutes G, the spirally-inclined division E, and sides D, when constructed and arranged for joint operation, as herein described.

i 2. I claim' the construction and arrangement of the plou'gh proper upon a secondary frame, in such a manner that thegplough maybe adjusted at varying inclinations, substantially as shown and described.
